SPECIFHJATION forming part of Letters Patent N0. 719,116, dated January 27, 1903. Application filed May 31, 1902. Serial No. 109,641. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN F. WV. HUEG, a citizen of the United States, and a resident of New York city, borough of Queens, State of New York, have invented certain new and useful Improvements in Dough Dividing and Shaping Machines, of which the following is a specification.

This invention relates to a machine that receives the raised dough, rolls it out, divides it up into the bulk desired, and molds it to 1 the required form.

In the accompanying drawings, Figure 1 is a side elevation of my improved machine; Fig. 2, a front elevation thereof; Fig. 8, avertical section on line 3 3, Fig. 2; Fig. 4 a rear View of the lower part of Fig. 3; Fig. 5, a detail of the gearing for adjusting the apron; Fig. 5, a detail of the spring setting mechanism; Fig. 5 a detail of the adjustable bearing for the feed-roller. Fig. 6 illustrates a modification of the stop-plate. Fig. 7 is a right-hand side View showing the dough rolling and cutting mechanism detached; Fig. 8, a section on line 8 8, Fig. 10; Fig. 9, a lefthand side View, and Fig. 10a front view thereof, partly in section; and Figs. 11 and 12 show different forms of the dough-molding drum.

The letter (t represents the frame of the machine, and ct is the hopper, into which the dough, to be first rolled and divided and to be then molded, is introduced. In order to gradually sheet the dough discharged from the hopper and to draw the same through the machine,thero are hung in the frame or, below the hopper a, a suitable number of drawing or feed rollers 12 1) b 0 c, and d d. The rollers b b are opposed by the roller 19*, which is mounted in adjustable bearings 19 so that the thickness of the dough may be regulated. The bearings b are adjustable by means of hand-wheel Z), having pinion If, that intergears with pinions I) of the screw-shafts b", engaging the bearings 12 Fig. 5 The rollers c o and cl cl are respectively opposed to one another and are designed to gradually compress the dough A and deliver it to the molding mechanism, hereinafter described, in

a flattened form, as shown in Fig. 3. To prevent an undue lateral spreading of the dough, the rollers c d are flanged at their ends, as at c (7- These flanges are sunk into the frame, which is spread laterally to accommodate the same. Some of the rollers are hung in pockets e, having bottoms, the lower edges of which are arranged tangentially to the rollers to constitute scrapers. These pockets are filled with flour for dusting the rollers. From the first set of rollers 11 b b the dough is guided to the rollers c c by a plate f, while a second plate f guides the dough from the rollers c c to the rollers d d. The feed-rollers are driven from a power-pulley g, mounted upon the shaft g of roller d. This shaft is integeared with the shaft of roller d by wheels 01 d Shaft g transmits motion to the shaft of roller 0 by chain g said shaft imparting motion to the shaft of roller 0 by wheels 0 0 The roller 1) is driven from the shaft of roller 0' by the chain g and in turn transmits motion to the adjustable roller b by long-toothed gear-wheels b b that permit the adjustment of bearings b without coming out of gear. The roller 19 transmits motion to roller b by long-toothed gear-wheels b b. Between the first and second pair of rollers is arranged an adjustable rotary cutter, that divides the dough into the lengths desired. This cutter is composed of an angular shaft h, hung parallel to the rollers and having flattened faces, from which the cuttingblades'h project laterally. The cutting edge 7L2 of each blade h is formed parallel to the axes of the feed-rollers and of the shaft h and engages the dough sidewise-z'. e., at about right angles to its plane of feed. The drawings show a four-sided shaft having for outters, so as to cut off four pieces during each rotation. By removing some of these cutters the length of the severed pieces may be readily changed. The shaft it receives its motion from the shaft of roller 1) by gear-wheels k 71 the ratio between which determines the speed of rotation of the cutters. By changing this ratio through the substitution of another set of gear-wheels the rotation of the cutter may be accelerated or retarded in order to sever smaller or larger pieces of dough. The cut off and flattened dough is delivered from the last pair of rollers d d by a guideplatef to the mechanism fol-molding it into the form desired for baking purposes. These means consist, essentially, of a rotating drum t, driven from shaft 9 by chain-wheels t" t and chain F. In proximity to this drum is hung upon a pintlej a catch or stop plate j, which is composed of a tapering upper section and a roughened lower section that projects beyond the upper section to form an offset or shoulder j. A pair of leaf-springs 70 hold the lower end of the platej against a stopj at the desired distance from the drum 7 These springs is, Fig. 5 are secured to a shaft 70, which may be rocked by means of a lever 70 and a set-screw k carrying a jam-n ut and impinging against fixed rod a so as to adjust the tension of the springs. The lower portion of the drum 'Zis surrounded by a curved apron Z,

I hung at one end upon pintle Z, while its other or free end is provided with means for setting it closer to or farther away from the periphery of the drum 7), so as to change the height of the passage B between the drum and apron. This passage is closed at both sides by the frame or by suitable flanges. The drum #1, as well as the apron Z, is covered with canvas. The means for raising and lowering the apron are shown to consist of a hand-wheel Z fast upon shaft Z carrying an eccentric toothed wheel Z which engages a rack Z formed upon the free end of the apron. Upon the shaft Z are mounted ratchet-Wheels Z engaged by pawls Z that may be lifted by hand-wheel Z If the eccentrio is thrown out of gear with the rack Z the apron will drop on hinge Z and permit the machine to be cleaned. The free end of apron Z is overlapped by a curved flange m, formed on the inner end of the delivery-table in, said table being movable in guides a of frame Ct. A set-screw m having hand-Wheel m and turning in frame a,is adapted to move the table along its guides, so as to change the distance between the flange m and the periphery of drum 2'. The relative adjustment between apron Z and flange m should be such that the flange will always lie fiat upon the upper face of the apron and form, in effect, a continuation of the same, so as to conduct the dough from the apron upon the table m. The end of the piece of dough A, delivered by rollers d cZ over guide-plate f is caught or intercepted by the offsetj of stop-platej, so that the dough will sag above the offset, Fig. 3. This sagging portion is caught by the rotating drum 2', which gradually rolls the dough up into a spiral A as the dough is forced downward between the drum and the roughened lower section of platej. During this operation the plate j is pushed away from the drum against the action of springs 7t, so as to discharge the dough-cylinder A into passage B. The further rotation of drum 2' will feed the dough-cylinder A along the passage B, so as to give it a true and smooth surface, until it is finally delivered upon the table m ready to be raised and baked. By changing the form of the working surface of the drumtdifferent configurations may be given to the bread. Thus in Fig. 4 is shown a plain cylindrical surface, while in Fig. 11 a double concave surface, and in Fig. 12 a single concave surface is illustrated. These configurations are obviously open to an indefinite number of variations.

In Fig. 6 is illustrated a modification of the catch-platej, said plate being here shown to be replaced by a corrugated roller a, working in conjunction with a plain roller 71. The end of the dough is curved first sidewise by roller 17, and thence upward by roller a, so that the dough is gradually rolled up into a spiral shape by the rotation of the rollers. The relative position of the rollers is such that after the dough has been completely rolled up it will fall 01f the roller 01 by gravity, to be thence taken along through passage B by drum 7 It is obvious that the mechanism for rolling and cutting the dough may be mounted in a different frame from that which carries the mechanism for molding it. In Figs. '7 to 10 the dough rolling and cutting mechanism is shown detached and supported bya separate frame. This mechanism is of the same construction as that shown in Figs. 1 to 3, motion being imparted to it by a chain A pointer 0, secured to the adjustable bearing 11 and moving along a scale serves to gage the quantity of dough delivered to the cutters.
